Zusammenfassung:	The utility model discloses a fixing structure of a heat exchange surface in a waste heat recovery flue. The fixing structure comprises an upper beam and a lower beam, wherein the upper beam and the lower beam are fixed on a heating surface. The fixing structure is characterized in that an upper guard plate and a lower guard plate are respectively arranged on windward sides of the upper beam and the lower beam. The upper guard plate is of a U-shaped structure. The lower guard plate is of a V-shaped structure. Wear-resistant alloy layers are overlaid or sprayed outside the surfaces of the upper guard plate and the lower guard plate. According to the utility model, the upper guard plate and the lower guard plate are arranged on the windward sides of the upper beam and the lower beam; direct eroding of flue gas on upper and lower beams is reduced through the guard plates; and the risk of fracture, which is caused by wear, of the beams of a water-cooled wall is reduced.
